Analysing long memory and volatility of returns in the Athens stock exchange

Abstract

A recent paper by Barkoulas et al. (Applied Financial Economics, 10, 177–84, 2000), examining long memory of returns in the Athens Stock Exchange (ASE, hereafter), finds evidence in favour of long memory. In this paper, long memory of returns in the ASE along with volatility are examined, using an ARFIMA–GARCH model, estimated via conditional maximum likelihood (ML, hereafter), and find weaker evidence in favour of long memory.
